Isolated dorsal epithelium from a bullfrog tongue decreased in transepithelial resistance across the tissue during the generation of the transepithelial response to salt. The resistance was measured by two methods. In one method, the resistance was measured by the electrotonic potentials which were caused by repetitive pulse currents of constant strength applied through the tissue. In another method, the current-voltage relation (I-V relation) was obtained from the electrotonic potentials caused by various pulse currents in strength and direction and from the currents applied. The resistance was measured by the slope of the I-V relation. The resistance determined by both methods decreased with increasing salt concentration, and this was almost in inversely parallel with the magnitude of the transepithelial response. Sodium transport across the lingual epithelium may be an early event in salty taste transduction.
